Worked Solution
Step 1: Convert the timer duration to seconds. 5 minutes × 60 = 300 seconds.
Step 2: Find the total time used. 2 min 47 s = (2 × 60) + 47 = 167 s. Total time used = 167 + 98 = 265 seconds.
Step 3: Find the remaining time. 300 − 265 = 35 seconds.
Answer: 35 seconds
Correct answer: 35 seconds
